I actually managed to overheat in ST5 once. It was a hot day and I was climbing a %20+ grade on S, pushing it, towards the end of a ride. It disabled Sport for some time. The good news is in mode 3 it never gets hot. Since St7 is heavier I guess it makes it easier in hot weather. How is the...

Finally something different and it seems great and that is only a test bike.

Looking great Ravi. I guess 500W is the nominal power right? 1kwh battery is great. since Ravi is a battery expert it gives me more confidence over the other offerings on the market. What is the overall weight of the bike?

Following Rich's gracious introduction to the forums, I believe we can now proceed to address the question posed by OP. Most of the mainstream torque sensing bikes from big brands are pedal assist only. You will have that option in smaller brands like Juiced have both torque sensor and...

It is baffling to see that putting lives in danger, breaking every traffic rule possible is considered as mimicking bike messengers' regular job definition. He recorded the crime and posted it on youtube and nothing happens, shhh.

Looks great. Always liked pinion and this is a game changer.

That experiment makes no sense(50 miles, wipe down ?). Btw the WS2 while being a dry lubricant is also used as an extreme pressure additive in wet lubricants such as motor oils. https://lowerfriction.com/dry-solid-lubricant-powders/tungsten-disulfide-ws2-powder/ However even in dry from it...

Now matter how much you clean outside of the chain, it won't do anything for the accumulated debris inside this is not even a matter of debate. If one is so skeptical all needs to be done is after cleaning outside of the chain dropping it in a jar of degreaser and shake it. After that run a...

Believe or not, contamination does work its way into the bushings. When you clean a chain, if it was just the metal on metal wear then all the gunk should have been magnetic but it is not, only a portion is magnetic. More importantly in the controlled experiments where chain is sprayed with...

It is not a chain lube brand. He seems to sell several brands of lube on his website and may be biased. That being said I did my own experimentation as I have explained in my original post and it mostly aligns with his results. Maybe instead you should understand that tests of spray lubes on...

That is well known and documented. External contamination is the major source of chain wear on bicycles. One site you can visit for a comparison is Zero Friction Cycling, you can check the wear rate between contamination vs no contamination. You should also check ZFC, those tests for bicycle...

Yeah I looked at those and they are best for sealed motorcycle chains. It seems to keep the outside clean but it can't penetrate and stay on a bicycle chain as well as paraffin.

3 rainy rides during the last 220 miles and my last waxed chain is still reasonably quiet, everything is clean. I can probably go further. So wax+ws2 mix is good for rain much better than any so called dry/clean lube I have ever used. So far ws2 has been better than ptfe in terms of longevity...

That is a pretty good offering, 720wh battery, rack,, fenders and Cannondale is a good brand. This can be a great commuter plus it is available at REI which is very convenient.

Not easy to answer without knowing how many amps does Stromer allow at maximum regen. Given your battery is not fully charged (if so regen will not work), and suppose Stromer maxes out at 10A of regen current you can absorb around 500W of power. From my personal experience, I used it many...
